Answer / anirban dasgupta

Considering ratio for m20 concrete as 1:1.5:3.
Cement content of 1m^3= 0.18m^3

Considering w/c ratio as 0.45. Water content is 0.081m^3 which when converted to litres gives 81litres.

Answer= 81litres with above assumed parameters

Answer / sabeer

Ratio of M20 concrete- 1:1.5:3
Volume of cement in 1 m3 concrete= 1/5.5 = 0.1818 m3
Weight of cement = 1440*0.1818 = 261.8 kg
Water cement ratio of m20- .45
Quantity of water = 0.45*261.8= 118 litre

Answer / fathi abu sabha

20N/MM2 = 200KG/CM2 CMPRESSIVE STRENGHT
THE WATER FOR 200KG/CM2 = 1/2 OF CEMENT QY 1/2* 200KG = 100
LITTERS
FOR 30N/MM2 = 300 KG/CM2 = 1/2*300KG = 150 LITTERS

Answer / mittal

mix m20
compressive strength -20n/mm2
200kg/cm2
i.e -0.5 ratio per 50 kg cement bag
for m20 making of concrete 1cum
9 bags cement in 1cum
25 liters per cement bag = 25*9= 225 liters
